Specification of Letters Patent.

Patented J une16, 1914.

Application filed January 10. 1913. Serial re ames.

To all whom it may concern:

; Be it known that I, WILLIAM M. REM- INGTON, a citizen of the United States, residing at Springfield in the county of .Hampden and State of Massachusetts, have invented certain new and useful Improvements in Water-Pumps for Automobiles, of which the following is a specification.

This. invention relates to improvement-s in water pumps for automobiles, and has for its object to provide an improved form of pump for use in circulating the water used for cooling the engine.

Another object of the invention is to provide an improved form of bearings for such pump.

Still another object is to provide an improved means for cooling the bearings and maintaining them in a comparatively cooled state.

It has been the practice hitherto in connection with such pumps to provide one or.

. more grease cups for lubrication of the shaft water or other cooling fluid which is cirand bearings. Owing to the high speed at which suchpump operates and to the ordinary heated temperature of the water, grease or oil lubrication hasnot been found to be satisfactory.

. By my improved invention I have provided a construction which enables the cooling and lubrication of the bearings by the culated by the water pump. Other objects of the invention will be made apparent and set fort in the following specification and accompanying drawin gs, in which- L Figure 1 is a side elevation of my improved pump. Fig. 21is a sectional view thereof, taken on the line 22 of Fig. 1. Fig. 3 is a detail section, taken alongthe line- 3 3 of Fig. 1. Fig. 4 is a detail section, taken along the line 4-4 of Fig. 2; and Fig. 5 is a perspective detail view of 5 one of the bearings.

Like numerals refer to like elements throughout the drawings. My improved ump comprises a main section designated y the numeral 10, and a cover section designated by the numeral 11, the latter being provided with the offset peripheral portion 12 secured by the bolts or studs '13 to the flange portion 14 of the casing' 10, which is of conventional shape and provided with the usual peripheral out-let l5 gradually increasing in cross section from the starting point on the periphery of the casmg to the tangential portion 16 terminatmg m a coupling flange, as shown in Fig. 1. The casing is provided with an outwardly extending hub portion 18, constructed with an intake chamber 19 therein, with which communicates the intake 20, as shown in Figs. 1 and 2. Adjacent its extremity this hub portion is provided with a reduced end 21, in which is mounted the bearing 22, having the collar portion 23 abutting against the shoulder 24, as shown in Fig. 2. Out wardly of the bearing 22 in the reduced hub portion 21 is a chamber 25.

A duct or tube 26 leads from the interior of the intake 20 to the interior of the chamber 25, as shown in Figs. 1 and 2. The hearing 22- is provided with longitudinal grooves 27 in its inner surface. Outwardly extending grooves 28, communicating with grooves 27 are provided in the outer end of the collar 23, as shown most clearly in Fig. 5. v

The cover portion 11 of the casing is provided with an outwardly extending hub portion 30, externally threaded, as indicated at 31. Interiorly of this hub portion is mounted the bearing 32, somewhat similar to the bearihg 22, shown of greater length and inwardly inclined, as indicated at 33 at its outer extremity. This bearing 32 is provided with longitudinal grooves 34 in its inner periphery, communicating with outwardly extending grooves 35 in the outer face of the collar portion 36. At the opposite extremity of the grooves 34 is a peripheralgroove 37 communicating with the longitndinal grooves, as shown in Fig.- 4.

A shaft 40 is mounted transversely of the hub casing 'of the pump and is mounted adjacent its extremities in the bearings 22 and 32, as shown in Fig. 2. This shaft is centrally apertured, as indicated by the numeral 41, and has one end terminating inwardly of the end of the reduced hub portion .21. The aperture 41 in the shaft 40 is in communication with the chamber 25 at one extremity and at its other extremity communicates with the cross aperture 42 in the shaft 40, this cross aperture communicating and being held in alinement with the peripheral groove 37 The-propeller wheel 45 of the pump is I an apertured sleeve 48 securely fitting around the shaft 40, to which it is suitably secured by a taper pin 47, etc. This sleeve is provided adjacent its forward portion, as shown in'Fig. 2, with a bearing 49 abutting against the end of the bearing 32, and at its otherextremity is provided with a bearing 50 abutting against the bearing 22.

This construction of the bearings and propeller Wheel serves to reduce friction at the points of contact,,and also providesfor maintaining the propellerand shaft against relative rotation with respect to the fan and pump casing. A stufiing box cap 51 is threaded over the end of the'hub portion 30 and has the usual inturned end portion 52, through which projects the shaft 22 and which serves to press against and expand the stufling or packing 53 to provide a watertight joint, as shown. i

The operation of the pump is similar to that of the ordinary centrifugal pump, the rotation of the shaft causing rotation of the impeller, which causes water or other fluid to be drawn in'through the intake and forces it out throughtheperipheral outlet. Owin cover plate 11 and to the adhesive and cohesive properties of the water the rotation of the impeller gives rise to a pumping ac- 'tion and the creation of a region of low pressure between said disk and said plate. As a result of this action, together with the suction "acting toward the intake chamber 19,-aproportion of the water delivered through the intake will be transmitted by or drawn through the small tube or duct 26 to the chamber 25, from whence a portion of it will flow through the grooves 27 in the bearing 22, and out through the end grooves 28 into the intake chamber 19. This will serve to preserve the temperature of bearing 22 at a comparatively low point and will prevent overheating thereof.

' bearing 32.

The portion of the water delivered tothe chamber 25 passes by virtue of the action of the "low pressure between the disk 45 and the cover plate 11, through aperture 41 in the-shaft 40 to cross aperture v42, whence it is delivered to the annular groove 37 and is discharged through the grooves 34 in the bearing 32, and outwardly through the end grooves 35 into the space between the front portion of the propeller and the casing cover, as shown in Fig. 2. This provides for the cooling and lubrication of the It will beapparent that in the operation of my improved pump I have provided for the reduction of friction between the propeller mounting and the bearings by the provision of the bearings 49 and 50. It will further be apparent that bycirculating a certain amount of the engine cooling fluid, as shown and described, the bearings will be suitably lubricated and will also be sufliciently cooled, and the amount of cooling fluid passing therethrough will be proportional to the speed of the impeller and shaft,
